Oxygen and the Infectivity of Romanomermis culicivorax
Abstract
The effects on itffectivity by preparasitic Romanomermis culicivorax resulting from four exposure times to four concentrations of oxygen at three temperatures were studied . Low oxygen (1.8 and 3.1 mg /liter) slowed losses of infectivity. Losses of infectivity were similar under aerobic (6 mg /liter) and microaerobic (0.4 mg /liter) conditions for the first 24 h but thereafter were slower in the microaerobic group. N interactions between temperature and oxygen were found over the ranges tested (15-27 C; 0.4-6.0 mg /liter). Key Words: Mermithid nematodes, mosquitoes, Culex pipiens, anoxybiosis.Downloads
